CAMERA,

SPECIFICATION forming part of Letters Patent No. 729,364, dated May 26,1903.

Application filed January 8, 1903. Serial No. 138,280. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE H. LEE, a citizen of the United States, and aresident of Omaha, in the county of Douglas and State of Nebraska, havemade certain new and useful Improvements in Cameras, of which thefollowing is a specification.

The object of my invention is to provide a means for preventing theaccidental or inadvertent-exposure of a sensitive film or plate whilethe bellows of the camera is folded but the camera-door open. Itsometimes happens that the careless or inadvertent pressure upon theshutter-working bulb will ruin an exposed film or prematurely expose asensitive film. My invention is designed to prevent this; and to thatend it consists, broadly, in an automatic shutter connected to andworked by the movement of the bellows in folding and unfolding, as willbe hereinafter fully described with reference to the drawings, in which-Figure l is a longitudinal section through a bellows-camera, showing infull lines the bellows partly extended and showing in dotted lines twoother positions of the bellows, the one being fully extended and theother fully closed. Fig. 2 is a rear view looking into the bellows fromthe sensitive film toward the lens.

In the drawings, A represents the framework of the camera.

B is the lens, and C the bellows connecting the lens to the framework.

Frepresents the sensitive film or plate behind the bellows.

My invention consists of two opaque wings J J of some lightinaterial-such as stiff black paper, hard rubber, or celluloid-which winare attached by glue orsmall rivets to the inner walls of the bellows.The edges of these wings are so caught in the plaits or folds of thebellows that when the bellows is fully extended and the plaits or foldsare drawn out nearly straight these wings lie fiat against the walls ofthe bellows, as indicated by the dottedlines J A J A, which permits thefull image of the lens to bethrown onto the sensitive film or, plate F,and when the bellows is fully folded the position assumed by the plaitsor folds of the bellows causes these wings to lap fully across thefield, ,as shown in full lines in Fig. 2 and by the dotted lines J B J Bin Fig. 1, thus completely masking the film or plate from the lens, sothat iffthe shutter-bulb be accidentally worked it does not spoil thefilm. This action is acco1n= plished in a perfectly automatic manner bythe mere drawing out and shutting up of the bellows and by the mostsimple, reliable, and practical construction, costing only a trifle forits application to any camera.

I have shown two wings J and J as forming the preferable arrangement;but it is obvious that one, two, or more of such wings might beemployed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A bellows-camera having attached to the same a shutter connected toand automatically operated by the movement of the bellows in the act ofopening or closing the same substantially as described.

2. A bellows-camera having one or more wings attached to the interiorwalls of the bellows and arranged to be moved away from before the fieldwhen the bellows is extended, and to be thrown across the field when thebellows is shut up substantially as described.
